This weapon was first developed as a result of a specification issued by SIAS, the New Cordian Military's sabotage and assassination division. It fires a special bullet first designed by the Americans and improved by the Russians before being optimized by our ballistic scientists. The round uses a piston inside of the case to propel the round while containing the explosion. And because the bullet itself is subsonic, this means that this weapon is 100% silent, apart from the noise made by the mechanism. While not very effective at long range, this pistol still excels at its designed role: undetected target elimination at close quarters.
